On July 18, 2025, Shanghai Dingbo Heavy Industry Machinery Co., Ltd. (hereinafter referred to as "Dingbo Heavy Industry") once again received international logistics news: the European version coarse power hammer mill (PC4008-75 type) and double screw sand washing machine (LSX-920 type) have been loaded into the Shanghai factory and officially shipped to Shanghai Port, and will be sent to Southeast Asia to serve local large-scale sand and gravel aggregate production lines and construction waste recycling projects. This shipment marks Dingbo Heavy Industry's continued leadership in the export of high-end mining equipment and injects Chinese momentum into the green transformation of global infrastructure construction.

Technical Empowerment: European version of coarse grinding solves industry energy consumption problems

The European version coarse grinding powder (PC4008-75 type) exported this time is the "star product" of Dingbo Heavy Industry, specially designed for coarse powder processing in industries such as metallurgy, mining, and cement. The equipment adopts the principle of material layer grinding, which achieves material crushing through high-speed collision between the rotor and the hammer head, saving 20% -30% energy compared to traditional ball mills. Moreover, with the increase of raw material moisture, the energy-saving effect is more significant. Its core advantages include:

High efficiency and low consumption: The single machine processing capacity can reach 10-100 tons/hour, and the finished product fineness is ≤ 3 millimeters, meeting the high standard requirements of machine-made sand, concrete aggregates, etc;
Long life vulnerable parts: The hammer head and lining plate are made of high manganese steel alloy material, and the service life can reach 2-5 years when processing limestone, greatly reducing maintenance costs;
Environmentally friendly sealing design: The fully enclosed negative pressure operating system eliminates dust and meets the EU CE certification standards. It can directly connect with international environmental projects.
According to the technical director of Dingbo Heavy Industry, this batch of equipment will be used in a government led "Green Building Materials Industry Park" project in Southeast Asia, replacing traditional high energy consuming and inefficient grinding equipment in the area, and is expected to reduce carbon emissions by over a thousand tons per year.

Innovation breakthrough: Spiral sand washing machine achieves "zero loss" of sand and gravel cleaning

The double helix sand washing machine (LSX-920 model) that was launched synchronously is a "water-saving artifact" developed by Dingbo Heavy Industry for the pain points of sand and gravel cleaning. The equipment achieves efficient separation of sand, gravel, soil, and stone powder through the dual action of double spiral blade propulsion and reverse water flow flushing. The washing degree is increased by more than 15% compared to wheeled sand washing machines, and the sand loss rate is less than 5%. Its technological highlights include:

Large capacity design: Single machine processing capacity of 100-350 tons/hour, supporting 24-hour continuous operation, meeting the needs of large sand and gravel plants;
Intelligent sewage circulation system: equipped with sedimentation tank and filtration device, the water resource reuse rate exceeds 80%, and the daily water saving of a single line can reach 200 tons;
Modular structure: Core components such as screw shafts and transmission devices support quick disassembly and assembly, reducing on-site maintenance time to one-third of traditional equipment.
